Simply select the folders (directory) where these files are located.
The symbol directory set here is the default location where symbols are saved to when the Build Symbol command is selected and where Draft it looks for symbols when the Insert Symbol command is selected.
It is possible to change these settings to suit the type work you are doing. i.e store symbols for different types of drawing work in different folders so that the path could be quickly changed to access a particular set of symbols.
These path settings allow network drives/folders to be set so that groups of users can use the same data.
The Autosave directory can be changed although normally this is not necessary.
If enabled the Autosave feature can create a backup copy at the specified interval of the drawing(s) currently being edited. If the feature is enabled and for whatever reason Draft it shuts down unexpectedly (power cut, PC crash etc.) then the Drawing Recovery box will be displayed the next time Draft it is started.
